Optical transmitter-receiver module suitable for reducing crosstalk

摘要

An optical transmitter-receiver module includes: an electrically conductive platform substrate having a transmitter region and a receiver region; a first insulating film extending over the transmitter region and the receiver region of the electrically conductive platform substrate; a first electrically conductive layer having a first fixed-potential, and the first electrically conductive layer extending over the first insulating film; a second insulating film selectively extending over the first electrically conductive layer; an optical receiver circuit including a light-receiving device and existing over the second insulating film; an optical transmitter circuit including a light-emitting device existing on the first insulating film; and a first electrically conductive shielding member spatially isolating the optical receiver circuit from the optical transmitter circuit, and being electrically coupled to the first electrically conductive layer.
